Came to clear blocked gulley in patio. Alex arrived at the agreed time. Did the job swiftly and was careful not to track mud into the flat. Gave me good advice about getting other tenants to contribute to the bill. Invoice was exactly as quoted. Would definitely use again.

Drain blockage

Alex and John came round the day after I contacted them to sort out a blocked drain. They did an excellent job. My drains are over 100 years old and haven't been flushed since I moved here over 30 years ago. The drainpipe coming down from the roof was solid and I was concerned that I would need new pipework, but fortunately Alex and John used jets to free the drain pipe and the drains. They were friendly, honest and did a thorough job in less than an hour - I couldn't recommend them more highly.

Overflowing Drain

The external drain collecting the outflow from my kitchen and that of a neighbour was overflowing. I called Drain Flow Services as we previously had tree roots breaking into the drains and obstructing them. Alex visited the next day and cleared the blockage. A CCTV inspection of the pipes confirmed that they were intact and unaffected by roots. The team were efficient and friendly. The work was explained and the video of the pipes was played back to me. The price was clearly explained as was the cost of the CCTV inspection, which was done at my request. I had a problem with rattling pipes in my bathroom, which Alex looked at free of charge and identified as being due to a u-bend drying out.

I would 100% recommend Alex at Drainflow Services. Yesterday he changed a soakaway from draining into my garden to drain into the main sewer. This is not the first time Alex has put in new sewer pipes and drains for me, he also did sewer works for two new toilets earlier this year. On both occasions I was really pleased with how neat and tidy the jobs were done. He was really precise cutting through the existing concrete, only channelling out the absolute necessary space for the work to be done. The concrete that was laid afterwards when the new pipes were in had been done perfectly. I didn't have to wait long for either the quote or the work to be done. The quote was better than expected on both occasions. The clearing up after the work was excellent. Everything was left neat and tidy, the left over rubble was bagged and stacked aside safely and collected this morning. There was no extra clearing or cleaning for me to do. Alex is a very pleasant cheerful man and just gets on with the job in hand. I wouldn't hesitate to recommend Alex to anyone in the future.

Alex came to look at my blocked gully which I thought needed repair. He cleaned it, then put a camera down and showed me that there was cement at the bottom of the gully, and leaking joints, as well as the broken drain that I could see. He quoted me a price, and did the job over two days, well within the time he said it would take. Everything was finished to a high standard and there was no mess, although he had to dig a trench. Rubble was taken away and I now have peace of mind. Alex is efficient and courteous, helpful without being pushy, and I have no hesitation in recommending him.

Had an awful odour coming through our sink and shower drain in one of our bathrooms. Alex attended promptly as arranged, did a diagnostic and gave his honest feedback. Suggested options and I felt fully informed. There was no undue pressure at any stage. After Alex attended on another day, jet-washed our drains and the odour has vanished! Very thankful to Alex; we’ve probably saved a small fortune trying to find the odour source from inside the bathroom. Highly recommend Drain Flow Services!

Due to some unpleasant smells I contacted Alex and arranged a date for a drain survey.

This is the second time I've used Alex in four years to clear a blocked drain and the first thing to say is that he's a really nice, friendly guy. He knows what he's doing, does it with a smile on his face and is thoroughly professional. Today, he took one look and despite the drain being more severely backed up than we suspected, he just got on with it and stuck to the pre-agreed, very reasonable price. And he didn't just do the bare minimum, he went out of his way to trim some roots that were contributing to the blockage, without any fuss or talk of paying him extra. Other traders might have left those so they could get more work in the near future. He says he's been clearing drains for 20 years and I think that shows.

Alex was recommended to me because of a pest issue and a broken foul drain. He was so helpful and reassuring and came out quickly to do a CCTV drain survey for me, explaining in layman's terms what we were seeing on the screen, installed two steel rat flaps to the front and back of my property and also cleared out a rainwater drain to a soakaway that was blocked. I wanted to check my drains for any root incursion and also any further cracks - happily they were all intact! He came back a second time to replace my broken clay waste pipe with a plastic one which involved digging up my concrete path, and then re-concreting it afterwards, which he did extremely neatly. He took photos of his work underground as he went along so he could show me what he had done. It was such a relief to finally find a reliable, trustworthy, helpful and knowledgeable tradesman after previous disastrous encounters with a large plumbing company. I have no hesitation in recommended DrainFlow Services and Alex to others.

Visit for Blocked Drain
We called Alex as we were experiencing problems with the water levels in our toilets after they were flushed. Alex was easily contactable and arrived quickly within a couple of hours of us phoning. He was extremely polite and considerate. Having inspected our drains and finding that there was a problem at the boundary of our private and shared drains, he suggested we contact Thames Water. Alex wanted to ensure that we could have our problem fixed free of charge by our water supplier if possible and did not suggest carrying out work himself which may not have solved the problem and which we would have had to pay for. Alex was correct with his advice as Thames Water found a blockage in the main drain which they removed free of charge. I would happily recommend Alex to anyone who is experiencing problems with their drains.

I always try my best to use Which Trusted Trader to recommend an honest and trustworthy trader. As all the ones I have used so far I woukld recommend. I had severe blocked drains, bathrooms, appliances, kitchen sinks, showers etc. I chose Drain Flow service because of the good reviews and business was in same area as where we lived. Alex corresponded efficiently at all times and arrived on scheduled date and assessed the situation. I must say he was very professional and honest in his services and recommended the best options without having to do a full CCTV survey. He carried out the job, cleared the block drainage with water jet blaster and other plumbing tools. He also cleared three of the showers and bathrooms, which had poor draining over the last few months. Now we can have longer showers without worrying water overflowing from the shower tray. Alex was always friendly, helpful and polite and always recommended best approach in maintaining his job. The service charges were very good for the amount of work Alex carried out. He also maintained social distance at all times due to Covid-19. Thank you Alex.

He examined the piece of material which looked like a black broken pipe which had blocked the drain and said it was calcified scale. He then carried out a full CCTV survey of the house drainage and the drain down to the road. He showed me the screen (being careful to observe social distancing) to show that it was clear and that there were no other potential scale blockages.

I found Drain Flow's details on Which Trusted Traders and was very happy that I did. We had a problem with the office drainage system involving a build up over years of waste in the various drains on the premises with the added difficulty of vermin accessing the drains.

He was professional, knowledgeable in his field, kept me up to speed at each stage of the process and carried out each element of the work as planned, on time and on budget.

It still took a lot of elbow grease and some manoeuvring but he managed to unblock it much to my satisfaction. Highly recommend him very good.
